cause a problem with the mining practice? They oxidize ferrous iron (FeII) back to ferric iron (FeIII) thus helping to propagate the cycle in a positive feedback loop while contributing to the release of sulfuric acid They produce organic acids (e.g. lactic acid) during fermentations which lowers the pH of the environment They consume a large amount of the pyrite, thus making mining operations less profitable They excrete toxins that make the effluent uninhabitable for other species
